The J. Rockett Audio Designs Boing is a compact spring reverb pedal built to do one job: put the reverb of a classic Fender Deluxe Reverb amp on your pedalboard. Rockett describes it as "a simple one knob recreation of the classic Deluxe Reverb," and like the amp it models, that single knob just gives you more or less reverb1. There are no modes, no damping controls and no tone shaping: the whole pedal is one knob and one footswitch.
The company behind it, J. Rockett Audio Designs, is based in Nashville2, and the Boing is made in the USA3. Premier Guitar reported its announcement in May 2015 as the company's new BOING Spring Reverb4.
What it does to your sound
The Boing is aimed squarely at amp-style reverb rather than studio reverb. Premier Guitar's launch coverage quoted the maker's approach: "In contrast to most reverb pedals BOING uses a simple approach aiming at recreating amp" reverb, not the plate and hall sounds of a studio unit4. Guitar.com's Huw Price framed the design goal as giving "a non-reverb amp some atmosphere in a simplistic way that is easily c"ontrolled from the floor3. In other words, if you play a non-reverb amp and want the wash a Deluxe Reverb gives a clean signal, this is the pedal built for that job.
The single control is an oversized reverb level knob, and its size is part of the design: Guitar.com notes the oversized knob is what makes the level easy to adjust with your foot while playing3. Delicious Audio's listing likewise describes the pedal as having one knob (Mix) and one footswitch, on/off2.
| Control | What it does |
|---|---|
| Reverb level knob | More or less reverb, like the single reverb knob on a classic amp15 |
| Footswitch | True bypass on/off13 |
How it works: a PT2399 chip with an analog treble circuit
Under the hood, the Boing is a hybrid. Guitar.com's review explains that "Its circuit is based around the Accutronics PT2399 digital chip, and an analogue treble circuit has been added for sprin"g-style splash and bounce, along with early reflections3. Rockett's own product page lists the pedal as an analog/digital hybrid with a 60mA current draw1, while some retail listings describe the circuit type simply as analog5; the chip at the center of it is digital either way.
The PT2399 itself is a common choice in affordable delay and reverb circuits. Premier Guitar has described it as "a digital chip often used to more affordably approximate analog-echo tones"7. EarthQuaker Devices' technical writing calls it "quite versatile and a bit of a hybrid chip originally used in karaoke machines, car stereos, and surr"ound sound configurations in the late 90s8, and Aion FX notes that a PT2399 circuit is technically digital but warmer and analog-voiced, with characteristics similar to a tape delay unit, and cheaper and simpler to build than a BBD-based delay9. That analog-leaning character is a fair part of why the Boing can pass for an amp's spring pan rather than a digital reverb algorithm.
Power and bypass
The Boing runs on 9V DC with a center negative tip and a 5.5mm x 2.1mm jack1. It is strictly a nine-volt pedal: Guitar.com reports that running it at a higher voltage voids the warranty3. Current draw is 60mA15.
The 9V center negative requirement and 60mA draw mean the Boing runs fine on a standard pedalboard power supply, but running it above nine volts voids the warranty35.
Switching is true bypass, per Rockett's product page1 and Guitar.com's review3. The reviewer checked the bypass path directly and found "There was barely any difference in tone, whether the guitar signal was passing through the Boing or not," concluding the pedal does not suck tone from the dry signal3.
Where it came from and what reviewers said
Premier Guitar announced the Boing in May 2015 as J. Rockett Audio Designs' new BOING Spring Reverb, "a very simple single knob reverb designed to emulate the classic reverbs of past"4. Delicious Audio covered it the same week, noting the maker is based in Nashville2, and later listed it at $159 in March 20186. Guitar.com's UK review gave the price as £1493.
Guitar.com's Huw Price reviewed it in September 2015 and came away positive, describing it as a digital spring reverb emulator styled after the spring reverbs integral to the amps the designers grew up with, and finding the bypass transparent3. Delicious Audio's own verdict was short: "LUVin the BOINGGGGGG......................nice reverb."2
"There was barely any difference in tone, whether the guitar signal was passing through the Boing or not."

Questions
Is the J. Rockett Boing analog or digital?
It is a hybrid. The core of the circuit is the Accutronics PT2399 digital chip, and J. Rockett added an analog treble circuit for spring-style splash and bounce along with early reflections. Rockett's own product page lists the pedal as an analog/digital hybrid, while some retailer listings describe it simply as analog.
Is the Boing true bypass?
Yes. Rockett Pedals lists true bypass switching for the Boing, and Guitar.com's review confirms a true bypass footswitch. The reviewer found barely any difference in tone whether the guitar signal was passing through the pedal or not.
What power supply does the Rockett Boing need?
It runs on 9V DC with a center negative tip, using a 5.5mm x 2.1mm jack, and draws 60mA. It is strictly a nine-volt pedal: Guitar.com reports that running it at a higher voltage voids the warranty.
Can the Boing reverb level be set with your foot?
Yes. The pedal has a single oversized reverb level knob, and Guitar.com's review notes the design makes the level easily foot-controllable, so you can push the knob with your foot while playing.
Where is the J. Rockett Boing made?
